Abstract (en)
[origin: US2019214977A1] A compensated comparator is provided, including a decision stage and a differential stage provided with two transistors connected by their sources, the differential stage being provided with compensation means to compensate the effects of a dispersion of the threshold voltages of the transistors forming the differential stage, the compensation means including first and second capacitors each connected to a gate of one of the two transistors, and being configured to memorize a voltage that is a function of a threshold voltage of the considered transistors.
Abstract (fr)
L'invention concerne un comparateur compensé (100). Notamment, la présente invention concerne un comparateur qui comprend un étage de décision (200) et un étage différentiel (300) pourvu de deux transistors (M1, M2) reliés par leurs sources S .L'étage différentiel est pourvu de moyens de compensation destinés à compenser les effets d'une dispersion des tensions de seuil des transistors (M1, M2) formant l'étage différentiel.Notamment, les moyens de compensation comprennent un premier et un second condensateurs (C1, C2) chacun connecté à une grille (G1, G2) d'un des deux transistors (M1, M2), et destinées à mémoriser une tension fonction de la tension de seuil des transistors (M1, M2) considérés.
